Abstract
The utility model discloses a novel continuous ball grinder for superfine grinding, belonging to power processing equipment. The inside of a traditional continuous ball grinder is respectively provided with a ball-stopping plate near to a material inlet and a material outlet, so that the filling rate can be increased to from 60% to 85%; the rotary rate of a barrel body of the ball grinder has a lower rotary rate of from 20% to 60%. The grinding capacity of grinding media can be effectively exerted for increasing the output of the grinder. The filling rate can be improved for decreasing the centroidal eccentricity during the rotary motion of the grinding media; the utility model partly balances out the increase of the moment of torque or the input power of the grinder needed by the rotation of the grind due to the increase of the filling level.
Description
Technical field
The utility model is to belong to the powder process equipment, particularly a kind of novel continuous ball mill that is used for high fine lapping.
Background technology
Among present industrial mineral and other raw material deep process technology fields, ball mill is a common visual plant; It is widely used in the grinding process of the common fineness of industries such as mine, metallurgy, chemical industry, building and electric power; It has simple in structure, running rate advantages of higher; But also there are a series of problems such as, power consumption height low such as work efficiency, in high fineness process of lapping, its above-mentioned weakness seems particularly outstanding, because of considering in the common crushing process in the mill medium ball to the impact grinding effect of bulk materials, the filling rate of traditional continous way ball mill is no more than 40%, the drum speed rate reaches more than 70%; When high fine lapping operation, need to strengthen the abrasive action of medium ball to material, rather than percussion; The operating efficiency of tradition continous way ball mill is very low, and effectively utilization rate of electrical only is about 2%, and its grainding capacity is not in full use.
Summary of the invention
The purpose of this utility model is a kind of novel continuous ball mill that is used for high fine lapping that proposes at the problem that prior art exists.Described traditional continous way ball mill, form by grinding mill barrel, input and output material quill shaft, abrasive media, bearing, it is characterized in that: each is provided with the grate plate of blocking that has tapered openings near the feed inlet and outlet place in the inside of grinding machine, when making things convenient for material turnover grinding machine, the grate plate of blocking is run out of or stopped up to abrasive media in preventing to grind.
The utility model and existing technology relatively have following beneficial effect: that sets up in grinding machine that the grate plate of blocking makes filling rate is increased to 60～85%, using rotational speed rate simultaneously is the rotational speed rate of 20～60% lower ball mill barrel, brings into play the grainding capacity of small size abrasive media effectively and increases mill output.The raising of filling rate can reduce the eccentric throw of abrasive media center of gravity when rotating, partial offset rotate needed moment of torsion or grinding machine input power because of loading increases grinding machine.The utility model adapts to the technological transformation of existing ball mill, and it is used for high fine lapping process effectively.
Description of drawings
Fig. 1 is the generalized section of ball mill.
Fig. 2 is the structural representation of the grate plate of blocking among Fig. 1.
The specific embodiment
Figure 1 shows that the generalized section of ball mill.Among the figure, on bearing 2, set up feed quill shaft 1 and discharging quill shaft 6, feed quill shaft 1 and discharging quill shaft 6 connect to form the grinding machine shell with cylindrical shell 4, the grate plate of blocking 3 is supported in the feed inlet and outlet front of interior feed quill shaft 1 of grinding machine shell and discharging quill shaft 6, on the grate plate 3 of blocking, also have a plurality of tapered openings 7 (as shown in Figure 2) that distribute according to concentric circles and radial rule, prevent of the obstruction of abrasive media bead when making things convenient for granular material to pass through to aperture, when material enters in the grinding mill barrel 4 through the material feeding end quill shaft 1 that is erected on the bearing 2, by grate plate 3 and abrasive media 5 mixed grinding in cylindrical shell 4 of blocking, abrasive media 5 is under low drum speed rate situation, be in the state of rolling, to the material surface is that the grinding of formula is peeled off in friction, high fill-ratio increases the grinding probability of medium to material down, make material attenuate fast, the fine powder behind the mill is blocked by discharge end outside grate plate 3 and the discharge end quill shaft 6 discharge mills.
Claims (2)
1. novel continuous ball mill that is used for high fine lapping, described continous way ball mill is made up of grinding mill barrel, input and output material quill shaft, abrasive media, bearing, it is characterized in that: each is provided with the grate plate of blocking that has tapered openings near the feed inlet and outlet front in the inside of grinding machine.
2. according to the described novel continuous ball mill that is used for high fine lapping of claim 1, it is characterized in that: the tapered openings on the described grate plate of blocking distributes according to concentric circles and radial rule.
